The control operation of the CPU 10 for preventing the forgotten wire device 100 will be described with reference to the flow B1 of the 3 |H to 5th. When the screw is tightened, the work is performed by the display unit 3 and the operation input J' is used for initial setting. The initial setting data is the setting of the number of points A and B of the screw to be tightened, and the setting information of the tightening screw predicting timer described later, and is stored in the memory unit 5 in step S1. In step S2, the CPU 10 is used to turn on the full-spinning completion signal described later, and the setting contents are read out from the storage unit 50 in step S3. Thereby, the initial setting is completed. Moreover, it is placed on a predetermined workpiece/platform by an operator. However, it is not necessary to have a full-screw-complete signal transistor to prevent the device 1 that is forgotten to tighten the screw. Step S 2 (and step S 2 4 described later) is required, but in the embodiment, the plurality of accessory connections are described using a possible use of a device for preventing forgetting to tighten the screw. In this state, if the CPU 10 is in step S4 and the workpiece signal is input, it is judged that the workpiece is placed on the workpiece (workpiece mounting table). Next, the process proceeds to step S5, and the communication number is output to the power supply unit 60, and the power is supplied to the electric screwdriver. Therefore, the electric screwdriver 60 is the use CPU 1 0, and then in step S 6 ' according to the workpiece recorder, the electric control screw is started, the number of 20 points is set, and , transistor CPU1 0 will use the workpiece for this, no, yes, for the device signal • the platform will supply power 200 status. If it is separated, in step S7, the power supply 〇FF signal is output to the power supply unit 6 0 ' further, in step S8, a bad signal is output, and a warning is displayed on the display 3 0. Was taken off. If there is a warning caused by a bad signal, 'Return to step s 4, the operator reloads the workpiece' to make the processing of c p U 1 0 and the operator's tightening screw work. When it is determined that the workpiece is not separated, the process proceeds from step S6 to step, and by monitoring the component (A) signal, it is determined whether or not the component A is taken out. When the part A is taken out, the process proceeds from step s9 to step s i 〇. In step S 1 0 ', the number of remaining points of the part A is reduced by one. Further, when the work is performed in the state of the pass, the new part A or the part b is not taken out until the screw tightening of the part is completed, and in the present embodiment, the step S 2 is passed because there is no predetermined part C taken out. 1 'S 6, S 1 1, S Perform the tightening screw operation of S 1 4~S 1 9 . In this & tightening operation, first, in step s 14 4, the electric screwdriver 2 0 〇 determines whether or not to rotate. When the electric screwdriver 2 〇 〇 is not rotating, return to step s 6 , in the case of rotation, proceed to step S 15 and start tightening the screw prediction timing. This tightening wire predicts the timing end time of the timing, which is preset in accordance with the screw length in step S1. Thereafter, in step S16, the electric screwdriver 2〇〇 again determines whether or not to rotate. This is because a momentary interruption is detected on the way of tightening the screw, or the screw is engaged to stop the rotation. When the electric screw is 2 〇 〇 without rotation, return to step S 6. When the electric screwdriver 60 is rotating, in step s丨7, the tightening screw predicts the timing to determine whether or not the time is over. At the end of the time, the 13th wire snail of the S9 constant 5 is the test piece rotation condition 17 - 1258063 (15). In step S] 8, the electric screwdriver 2 〇〇 is to determine whether it is rotated or not. In the case of no rotation, in step S] 9, the torque increase signal is to discriminate whether or not to input. The torque boost signal is generated by the electric screwdriver 2 〇 预定 within a predetermined time of reaching the predetermined screw torque. When the torque increase signal is no input, it means that the electric screwdriver 60 is idling, and the process returns to step S6. When the torque increase signal is an input, this means that the screw is normally tightened 'by this'. In step S20, the number of remaining points of the screw is reduced by one. For the completion of the tightening of the part Α, tighten the screws in the same place. When the tightening screw of the same part is completed, if the number of points to be mounted of the part A is 2 or more, the next part a is taken out, and the number of parts is subtracted from the number of parts in step S 1 0, for this new The removed part a ^ is tightened in the same manner as described above. In this way, if all the pre-set component points of the part A are tightened, the same parts are taken out and the screws are tightened for the part B. As described above, in this embodiment, although only the parts A and B are set to be attached to the workpiece, it is possible to mistakenly take out the part C, and in step S13, 'the parts of the part take-out detector from the part C are also monitored ( C) Signal. When the component C is taken out, the power supply OFF signal is output to the power supply unit 60 in step S7, and the bad signal is output in step S8, and the warning is displayed in the _not portion 30. In steps S 1 0, S 1 2 and § 2 〇, the subtraction result ' may be displayed on the display unit 3 as the number of remaining points of the parts A and B and the number of remaining points of the screw. However, in the above description, 'every 1 is subtracted from the number of points stored in the parts and screws -18 - 1258063 (16), it is judged whether it is zero, but it can be replaced by this, and the number of used points is counted and discriminated.値 It is also possible to reach the setting. When it is judged in step S 2 1, if the number of remaining points of the screw, the part a, and the part B is zero, the process proceeds from step S 2 1 to step S 2 2 ' of the fifth figure to disconnect the electric screwdriver 2 0 0 The power supply supplies the power supply 0 FF signal to the power supply unit 60, and in step S23, outputs a good signal indicating that the tightening screw is completely completed. The completion of this tightening screw is also displayed on the display portion 3G. The operator saw the completion of the tightening screw on the display unit 3 ,, and it was found that the screw connected to the device for preventing the screw was forgotten.] The screw of the electric screwdriver 60 of the 〇 动作 was completed. Thus, the operator takes the workpiece out of the workpiece platform. In step S24, the full screw completion signal is output, but since this embodiment is for the case where the device 100 for forgetting to tighten the screw is used alone, the full screw completion signal is not output to the outside. As will be described later, in the case where the device 丨00 for forgetting to tighten the screw is used alone, since the full screw completion signal is input, the process proceeds from step S25 to step S26. Moreover, since the workpiece is separated, it further moves to step S27, and the output of the good signal is turned off. Next, referring to Fig. 6 and Figs. 3 to 5 which have been described above, the case where the plurality of devices for preventing the forgotten tightening of the screws shown in Fig. 1 are attached will be described. In Fig. 6, n (but 'η is an integer of 2 or more) means 1 for preventing the screw from being forgotten (device 1, device 2. . . . . The device η) is attached, exemplified in these devices 1~η, the electric screw starts at 200 (electric screwdriver, electric screwdriver 2, electric screwdriver). . • Electric screwdriver η) is the case for the corresponding connection. -19 - 1258063 (17) However, for the sake of simplicity of explanation, in Fig. 6, the part to which the workpiece is attached is set in advance at the mounting position of the same workpiece, and for this case, only the tightening screw is displayed, and therefore, It is to be noted that the input of the component () signal for taking out the components of the device for preventing the screw from being forgotten is not shown. As in the above-described embodiment, the double/J operation of taking out the component and tightening the screw may of course be performed. However, when the part signal is not input, 'there is no need to be related to the processing steps of the parts of steps S 9 to S 1 3 of FIG. 3, and the discriminant of the parts related to step S 2 ] of FIG. 4 Also not needed. Moreover, it is also possible to connect some or all of the devices for preventing the tightening of the screws to the same electric screwdriver in place of the device for preventing the screw from being forgotten to be screwed. In the case where the device for forgetting to tighten the screw is attached, the device in the rear section can replace the workpiece signal to input a good signal from the device of the preceding segment. That is, the good signal from the device of the previous stage is as shown in Fig. 6, and the device sealed in the latter stage is recognized as the workpiece signal. Therefore, whether or not the device ' in the subsequent stage is the device good signal from the previous stage (which occurs in step S23 of Fig. 5) is equal to whether or not the workpiece signal is received, thereby being discriminated in step S4 of Fig. 3. Moreover, in step s 4, as long as it is not judged to receive a good signal, the subsequent steps are not carried out. Thus, in the device i in the latter stage, if the good signal from the device i-1 of the preceding stage is not supplied, since the power supply is not supplied to the electric screwdriver 1 , the screwing operation will not start. Therefore, even if the tightening screw is not displayed on the display unit 3 ,, the operation input memory is performed when the tightening screw operation of the front stage is completed -20 - 1258063 (18). If you forget to turn on the crystal phototransistor to complete the turn-on stage of Figure 6, set 1 to give the power supply to the screw to work properly, cut off the device 2 and fully screwed but complete The screw is completely screwed out). If the first signal, the operator can really know the problem of the previous part of the job is not required. Before the start, the operator will operate the device separately. In the step S, the initial setting data will be 11 and the whole screw will be used. The device for rotating the signal through the transistor to turn on the screw] is the state in which the light of the photocoupler PC is input when the full screw is completed. Therefore, if the device η of the final stage is to turn on the full screw to complete the signal Tr, the photocoupler of the device 1 to the device n-1 is turned on, and the device 1 to η-1 are in the state of no signal input. . Further, the workpiece is assembled to the workpiece sJ1 and supplied to the apparatus 1. When the device 1 detects that the power is supplied to the electric screwdriver 20 0 _ 1 , the supply portion 6 α is turned on (step s 5 ). Thus, the power is the donor 2 0 0 - 1. Further, under the control of the apparatus 1, if the rotation is performed, the power supply to the power supply electric screwdriver 2 0 〇 - 1 is supplied to the power supply (step s 2 2 ), and a good signal is generated (step S 2 3 ). In the step S23 of Fig. 5, the device 1 is used to output the other devices 2 to the device by using the Japanese-Japanese-Japanese-Japanese-Japanese-Japanese-Japanese-Japanese-Japanese Signal line (ie, for output). The transistor Tr for the signal is not connected to the other six, and only the device n from the final segment is transmitted to the g portion 50 of the other device η through the signal line L. In the anti-transistor, the output of the PC is the same as that of the whole workpiece, and the signal is supplied to the electric screw supply unit, and the device that sends the setting is turned off by the disconnection signal]~ the device η, 1 - 21 - 1258063 (19) The ground is set. However, as described above, when the photocoupler pC body of each device is in a non-conducting state, the full screw completion signal is formed. And 'When the device for forgetting to tighten the screw is used as a single unit', since the input terminal of the photocoupler is in the open state, the full-thread signal is input. Thereafter, the device 1 is in step S25 of Fig. 5, and the signal is transmitted by the L monitor, and the device η of the final stage judges whether or not the completion signal is output. When the full screw completion signal is output, S 26 ' determines whether the workpiece is separated. In the case of separation, enter the step and turn the good signal signal OFF. On the other hand, in step S25, when the full-spinning completion signal is determined, that is, the phototransistor PC's phototransistor is turned on, the process proceeds to step S28, and it is determined whether the workpiece is separated. In the separation case, step S2. 9 disconnects the output of the good signal, and outputs the communication number in the case of no separation, in any case, returns to the step. However, when the workpiece is separated, after the step S 2 9 is disconnected, When the process returns to step S28 by step S25, the workpiece is placed. In order to cope with this situation, the good disconnection will be turned on again in step S30. In the device 2, when the good signal (=work signal) is determined, the power supply of the electric screwdriver 2 is performed, and the setting operation is performed. As a result, the appropriate tightening screw operation is performed. The OFF signal and good signal will occur. After that, the same processing as the device is also performed. The light crystal is solidified and the signal line is fully screwed in the step S 2 7 when the input condition is not in the case, in the step S25 ° signal, and then the signal is supplied to the screw, the feeling of 1 22- 1258063 (20) Similarly, in the final stage device η, if the set rotation is properly traversed, the device η will output the full-twist tightening screw set by the good signal. Thereafter, in step S24, the full screw completion signal is output. The signal, the full-spinning of the device η completes the signal output transistor 71. And it is transmitted to other devices 1 to n-1. Thereby, the phototransistors of these 1 to η-1 are turned off, and in step S25 of Fig. 5, it is determined that the full screw completion signal is in the state, and the operator removes the workpiece from the workpiece stage. Thus, the respective devices 1 to η are discriminated in step s 2, and the output of the good signal is turned off in step S297.
